During operation, the vibrating disk 31 sequentially arranges and vibrates nuts through the discharge chute 32 and conveys the nuts to the material pushing chute 33, when the material pushing cylinder 34 is in a contraction state, the limiting block 371 and the material pushing rod 342 are respectively positioned at two sides of the opening of the discharge chute 32 to form the accommodating part 38, so that the nuts sent out from the discharge chute 32 are limited, the accommodating part 38 can only accommodate a single nut, and therefore the situation that only the single nut is allowed to enter the material pushing chute 33 one by one is realized, and then the material pushing rod 342 is utilized to push the single nut to enter the implanting mechanism 4, so that the reliable implantation of the single nut is realized, the situation that the clamping phenomenon easily occurs in the handpiece is prevented because a plurality of nuts are pushed into the handpiece at the same time, and the use smoothness of the direct vibration nut implanting machine is greatly improved.

The lifting component 42 drives the implanting mechanism 4 to lift, and the implanting cylinder 43 presses the nuts conveyed by the feeding mechanism 3 into corresponding positions of the plastic parts through the feeding pipe 44 and the heating component 45. The clamping block 462 can clamp the nut with the positioning block 461 under the pushing of the second pressure spring 465, the nut is pushed to the clamping assembly 46 from the feeding groove by the pushing mechanism and is clamped by the clamping assembly 46, the direction of the axis of the nut is kept consistent with the direction of the axis of the feeding pipe 44, and the nut is prevented from being turned over in the installation process.

Meanwhile, when the nut is pushed to the implantation mechanism 4, the clamping block 462 and the positioning block 461 clamp the nut; the implanting cylinder 43 pushes the nut into the feeding pipe 44, and the limiting edge 441 deforms to limit the nut, so that when the size of the nut is smaller than that of a standard nut, the nut can be prevented from directly falling from the feeding pipe 44; since the diameter of the material pipe is larger than that of the standard nut, when the size of the nut is larger than that of the standard nut, the nut cannot be clamped by the feeding pipe 44. Thereby improving the working stability of the nut implanting machine.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
